摘要：

In this paper, an improved control strategy combining backstepping and disturbance observer( DOB) is proposed. This control strategy mainly deals with the nonlinear and unknown disturbances of the pneumatic system. Moreover, the DOB is mainly used to estimate and compensate the external interference of the system. In addition, considering the actual application, the control system is more sensitive to the input signal. Therefore, a tracking differentiator(TD) is introduced in the backstepping controller to optimize the input signal of the system. Finally, the simulation results show that the control strategy proposed in this paper can effectively improve the position tracking ability of the system.
